A new animal study suggests a combination of green tea and vitamin B3 may combat brain cell deterioration. Researchers found the pairing helped restore energy to aging brain cells and reduced processes linked to Alzheimer’s disease. The study, conducted on animal models, indicated potential for reversing some effects of cognitive decline. However, experts caution that these findings are preliminary and cannot yet be applied to human treatments. Further research is needed to determine if the same benefits would be observed in humans and to establish safe and effective dosages. The findings offer a potential avenue for future exploration in the fight against neurodegenerative diseases, but remain in the early stages of development.
